commit 5081fc1c773d2a83ec7a867f030323b8b6956cd1

    xenfb: avoid reading twice the same fields from the shared page
    
    Reading twice the same field could give the guest an attack of
    opportunity. In the case of event->type, gcc could compile the switch
    statement into a jump table, effectively ending up reading the type
    field multiple times.
    
    This is part of XSA-155.

commit 74fab2ef4c0ba42af477e9e445c9883cc45cf9e6

    xen/blkif: Avoid double access to src->nr_segments
    
    src is stored in shared memory and src->nr_segments is dereferenced
    twice at the end of the function.  If a compiler decides to compile this
    into two separate memory accesses then the size limitation could be
    bypassed.
    
    Fix it by removing the double access to src->nr_segments.
    
    This is part of XSA-155.
